Kirsten rat sarcoma viral oncogene homolog G12V (KRAS G12V)

Target
KRAS G12V
Molecular classification
Small GTPase, Oncoprotein, Signaling protein
01

Overview

KRAS G12V is a specific point mutation in the KRAS gene where glycine at position 12 is replaced by valine. This mutation results in constitutive activation of the KRAS protein, leading to oncogenic signaling and tumorigenesis. It is prevalent in several cancer types, including pancreatic, colorectal, and lung cancer, and is associated with poor prognosis and resistance to EGFR-targeted therapies. Direct inhibition of KRAS G12V is challenging, but immunotherapeutic approaches are under investigation.
